WPI courses are structured in four terms; they are seven-week long, with a 10-day break between A and B Term, a month of Christmas vacation between B and C, and another 10-day break between C and D Term. While this structure makes courses very intense compared to other colleges, the fact that they last for only 7 weeks is refreshing and improves the students' quick-thinking ability. The courses are heavily based on practical work, research, public speaking, and travelling abroad. The class sizes vary, and while freshmen are often taught in big lecture rooms, they eventually develop stronger interactions with their professors, once their courses become more degree-specific. WPI is expensive, but it tends to be big on scholarships and financial aid, especially towards international students. Most freshmen live in dorms, which makes socializing easy, and then move to off-campus housing. Don't expect much from the Woo nightlife, but there are plenty of student parties throughout the year.
